How to make a NavMeshAgent follow a custom path?

Is there a way to make an agent move along a path that's not linear? I have a list of points that draw a cicular movement and I'd like the agent to go along that path.

How can I create a NavMeshPath with custom points?

 

Do you specifically need to create a custom path, or is it enough to get the agent move on a route that passes through those points? If that latter option is ok, you could probably think about using some basic patrol route style approach? Just make the agent travel from point to another; when it's close enough to the first point, set the next waypoint. And repeat until you have no waypoints left in your list. When you have many points it will appear as if it's not linear.

 

https://docs.unity3d.com/540/Documentation/ScriptReference/NavMeshAgent.SetPath.html

Assign a new path to this agent.

If the path is succesfully assigned the agent will resume movement toward the new target. If the path cannot be assigned the path will be cleared (see ResetPath).

It still linear, there is no path that is not linear, but you can play with angle velocity to smooth it.

More that that, disable agent position update, just move agent and set NavMeshAgent.NextPosition = transform.position

its all in docs

 

I can't create a new path with custom points.

Maybe there's something to be done with nextPosition.. I'll try it out and let you know.

 

I would like to try not doing it this way but it will be my last resort if there is no other way.

 

Sorry, I didn't pay attention you already said that there in no way to set Vecto3[] into NavMeshPath. Yes, there isn't.
So disable update is option number one https://docs.unity3d.com/2017.3/Documentation/Manual/nav-MixingComponents.html
And disable auto break number two: https://docs.unity3d.com/Manual/nav-AgentPatrol.html
or vice versa.

 

If the distance to your target is very big, the SetDestination will not work, but to solve the problem I recommend you to use NavMeshPath, you can make a function to build a path and then move along it until you reach your target

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
public class TestAgentIA : MonoBehaviour
{
public Transform target;
NavMeshAgent agent;
NavMeshPath path ;
private float elapsed = 0.0f;
int index = 0;
public bool DrawGizmo = false;
public Color GizmoColor;
public float radius;
// Start is called before the first frame update
void Start()
{
path = new NavMeshPath();
agent = GetComponent<NavMeshAgent>();

}

// Update is called once per frame
void Update()
{


elapsed += Time.deltaTime;
if (elapsed > 1.0f)
{
elapsed -= 1.0f;
NavMesh.CalculatePath(transform.position, target.position, NavMesh.AllAreas, path);
index = 0;
}
MoveToPath();
}
void MoveToPath()
{
if (path != null && path.corners.Length > 0)
{
float distance = (path.corners[index] - transform.position).magnitude;
if (distance <= agent.stoppingDistance)
{
index = (int)Mathf.Clamp(index+1, 0, path.corners.Length - 1);
}
agent.SetDestination(path.corners[index]);
}
}
private void OnDrawGizmos()
{
if (!DrawGizmo|| path==null) return;
Gizmos.color = GizmoColor;
for (int i = 0; i < path.corners.Length - 1; i++)
{
Gizmos.DrawLine(path.corners, path.corners[i + 1]);
if (index != i && index != i + 1)
{
Gizmos.DrawSphere(path.corners, radius);
Gizmos.DrawSphere(path.corners[i + 1], radius);
}

}
Gizmos.color = Color.blue;
Gizmos.DrawSphere(path.corners[index], radius);
}
}
